Can thatch be applied onto an existing structure?
Most other roofs are constructed at a pitch smaller than the recommended minimum pitch of 45 degrees . Should the existing structure be adapted for a thatch roof, it would need to be designed by an engineer and modified to attain the minimum angle required. Most thatch roofs in South Africa are constructed from poles and not sawn timber, the roof being exposed from the inside, unlike conventional roofs, which are fitted with ceilings.
